Abstract

This qualitative study explores the labor culture of siwalan farmers in Madura, Indonesia, highlighting how religious values and prayer practices are integrated into daily agricultural routines. Departing from conventional productivity metrics, it examines how adherence to Islamic principles particularly respecting prayer times defines work ethic and productivity within this community. Based on in-depth interviews and observations, the study reveals how spirituality shapes decision-making, work schedules, and attitudes toward labor. The findings emphasize the role of religious commitment in guiding agricultural activities, suggesting that spiritual fulfillment is central to productivity and well-being. This research contributes to a nuanced understanding of indigenous work cultures in Indonesia, especially how religious frameworks shape perceptions of labor beyond economic measures. Insights from this study are also valuable for policymakers and development practitioners engaging with agricultural communities, and they enrich broader academic discussions on the intersection of religion, work, and economy in non-Western contexts.

Abstract

Industri perhotelan di Surabaya menghadapi tingkat persaingan yang semakin ketat sehingga peningkatan produktivitas tenaga penjualan menjadi prioritas utama dalam menjaga daya saing. Penelitian ini bertujuan untuk menganalisis pengaruh kompetensi dan pengalaman kerja terhadap produktivitas sales hotel. Metode penelitian menggunakan pendekatan kuantitatif eksplanatori dengan responden sebanyak 40 tenaga penjualan dari hotel berbintang, dipilih melalui purposive sampling. Instrumen penelitian berupa kuesioner skala Likert yang telah diuji validitas dan reliabilitasnya, serta dianalisis menggunakan regresi linier berganda dengan bantuan perangkat lunak SPSS. Hasil penelitian menunjukkan bahwa kompetensi berpengaruh positif signifikan terhadap produktivitas (t = 3.217; p = 0.003) dan pengalaman kerja juga berpengaruh positif signifikan (t = 2.865; p = 0.008). Secara simultan, kompetensi dan pengalaman kerja memberikan kontribusi sebesar 71,2% terhadap variasi produktivitas tenaga penjualan (Adjusted R² = 0.712). Temuan ini mengonfirmasi bahwa sinergi antara kompetensi dan pengalaman kerja merupakan faktor determinan yang esensial dalam peningkatan produktivitas sales hotel. Penelitian ini memberikan kontribusi pada pengembangan manajemen sumber daya manusia di sektor perhotelan melalui strategi pelatihan berbasis kompetensi dan pengelolaan pengalaman kerja yang berkesinambungan.

Abstract

The use of small-scale solar energy is one of the strategic solutions for electricity needs in remote areas and outdoor activities. As the need for portable electrification increases, the development of solar backpack systems is becoming a practical and sustainable alternative. This research aims to design and test a portable backpack system based on a thin film solar panel with a capacity of 20 Wp, equipped with a 12V solar charge controller and a 7.2 Ah battery. The system is designed with two outputs, namely 12V DC and 5V USB, to support lightweight devices such as LED lights and smartphones. The test was carried out at two different locations, namely Mount Lorokan and Mount Penanggungan, with data taken which included latitude, longitude, solar elevation angle, PV voltage, PV current, and output power. The measurement results show that there is a variation in the performance of solar panels according to geographical conditions and solar elevation angles. On Mount Lorokan, the peak power reaches 8.55 W at an angle of 75°, while on Mount Penanggungan the maximum power is slightly higher, which is 8.6 W at an angle of 78°. Mount Lorokan excels at maximum power, Penanggungan shows more stable performance at low to medium angles. This research contributes to the development of a portable electrification system based on renewable energy that supports power continuity in locations without access to electricity.
